Hi,
I'm managing several mail servers running CentOS 7, Postfix and Dovecot.
SpamAssassin is filtering mail nicely, but I'm considering using RBL
(blacklists) to take some load off the servers.
General question to those of you who use RBL. Which lists do you
recommend using?
The best free blacklist that I'm aware of is zen.spamhaus.org. I've been using
it as
a blacklist on my server for years without any problems.
More info: https://www.spamhaus.org/zen/
Spmhaus isn't free per se.
